One person has been confirmed dead, nearly fifty climbers are severely injured, and ten people are missing after Mount Ontake (御嶽山, Ontake-san), a popular climbing spot in central Japan, erupted for the first time in five years. News coverage shows billowing clouds of ash, and a large climbing lodge at the top of the mountain covered in grey cinder.

YouTube poster kuroda terutoshi uploaded frightening smartphone footage of the initial explosion as it happened at the top of the mountain. “Let's get out of here!” he says, as a cloud of ash descends on the climbers.

At 3,067 m, Mount Ontake is the second-tallest volcano in Japan after Mount Fuji. It's located in Gifu, close to the large city of Nagoya in central Japan, and is a popular hiking destination in summer and early fall.

Due to the many missing and wounded, many people are looking for updates on the status and whereabouts of friends and loved ones caught on the mountain during the eruption.
